Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Agriculture

Gerard W. Wall spends much of his time researching Growing season, Agronomy, Agriculture, Climate change and Global warming. His Growing season research includes elements of Sensible heat and Evapotranspiration. His Evapotranspiration study combines topics in areas such as Canopy and Drip irrigation.

His research investigates the connection between Agronomy and topics such as Carbon dioxide that intersect with problems in Sorghum and Biomass. When carried out as part of a general Agriculture research project, his work on Crop simulation model and Agricultural productivity is frequently linked to work in Natural resource economics, therefore connecting diverse disciplines of study. His studies in Climate change integrate themes in fields like Food security and Greenhouse gas.

His most cited work include:

  • Rising Temperatures Reduce Global Wheat Production (801 citations)
  • Methodologies for simulating impacts of climate change on crop production (371 citations)
  • Field-based phenomics for plant genetics research (368 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Agronomy, Carbon dioxide, Botany, Canopy and Photosynthesis. His study ties his expertise on Soil water together with the subject of Agronomy. His Carbon dioxide study integrates concerns from other disciplines, such as Field conditions, Transpiration, Poaceae and Stomatal conductance.

His Botany research incorporates elements of Hydraulic machinery, Orange and Animal science. He has researched Photosynthesis in several fields, including Acclimatization and Horticulture. His Crop research also works with subjects such as

  • Yield most often made with reference to Agriculture,
  • Agroforestry most often made with reference to Climate change,
  • Global warming which connect with Sowing.

He most often published in these fields:

  • Agronomy (49.28%)
  • Carbon dioxide (27.54%)
  • Botany (26.09%)

What were the highlights of his more recent work (between 2016-2020)?

  • Agronomy (49.28%)
  • Crop (17.39%)
  • Soil water (14.49%)

In recent papers he was focusing on the following fields of study:

Gerard W. Wall mainly focuses on Agronomy, Crop, Soil water, Canopy and Phenology. His biological study spans a wide range of topics, including Agriculture, Agricultural productivity, Cultivar and Sowing. His Agriculture research includes themes of Climate change and Crop yield.

His research integrates issues of Fertilizer, Carbon dioxide and Irrigation in his study of Cultivar. Gerard W. Wall focuses mostly in the field of Canopy, narrowing it down to topics relating to Energy balance and, in certain cases, Semi-arid climate. His Phenology research is multidisciplinary, relying on both Yield, Agricultural engineering, Growing season and Water content.

Between 2016 and 2020, his most popular works were:

  • The uncertainty of crop yield projections is reduced by improved temperature response functions. (99 citations)
  • Crop Model Improvement Reduces the Uncertainty of the Response to Temperature of Multi-Model Ensembles (66 citations)
  • Canopy temperature for simulation of heat stress in irrigated wheat in a semi-arid environment: a multi-model comparison (57 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Agronomy

His primary areas of investigation include Agronomy, Yield, Arid, Heat stress and Grain filling. The Agronomy study combines topics in areas such as Agricultural engineering and Climate change. His Yield studies intersect with other subjects such as Atmospheric instability, Semi-arid climate, Canopy and Energy balance.
